Studies show that up to 87% of endurance athletes are physically impaired during their workouts and competitions due to dehydration, despite ample access to fluids. Dehydration causes the following physiological phenomena.
⬢ Decreased blood pressure
⬢ Increased heart rate
⬢ Increased respiratory rate
⬢ Decreased blood flow to extremities
These physiological changes can lead to cardio-respiratory stress, impaired thermoregulation, and fatigue – all of which have a significant impact on athletic performance.
Because the symptoms of mild dehydration are subtle – often imperceptible – athletes suffer the consequences without always knowing it.
Proper hydration is central to feeling energized and motivated. Fatigue and physiological strain manifest at dehydration levels as low as 2%, making a workout feel sluggish and heavy-legged. This not only leads to an athlete feeling flat and listless, but also compromises the quality of the workout and training potential.
Studies show a significant drop in performance at mild dehydration levels as low as 2-3%. This impairment manifests itself in multiple ways.
